The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, 2, a kind of turnbuckle is equipped with screw rod 8 in the middle of comprising degree of tightness body 1, degree of tightness body 1, slide block 4 is contained on the screw rod 8, the head of screw rod 8 is equipped with U-shaped jaw 5, bearing pin 7 by pin 6 location is housed on the jaw 5, also include locking gear 2, described locking gear 2 is a ratchet device, is installed in the end of screw rod 8 and is clipped between two bars of degree of tightness body 1 by bearing pin 3; Comprise gear 21, gear cover 22, locating piece 23, described locating piece has two ball-shaped grooves 241 for 23 times, 242, locating piece 23 can promote back and forth along the line direction of two grooves, in the bottom of locating piece 23 lock screw 26 is housed, lock screw heads into steel ball 27 in groove 241 or the groove 242 by spring 25, locating piece 23 and gear 22 are engagement when steel ball 27 heads into groove 241, locating piece 23 and gear 22 are non-engagement state when steel ball 27 heads into groove 242, during use, promote locating piece 23 before tightening up and be pressed into groove 242 positions to steel ball 27, tightening up 23 of promotion location, back makes steel ball 27 be pressed into groove 241 positions, locating piece 23 and gear 22 engagements, gear 22 is when clockwise rotating, gear 22 laterally promotes steel ball 27, this moment, steel ball was stressed to be moved downward, gear 22 is rotated, steel ball 27 is in the pressing groove 241 that resets of spring 25 then, gear 22 is when rotating counterclockwise, gear 22 is pressed locating piece 23 downwards, because of locating piece 23 is withstood and can't move,, make that gear can only be towards the rotation of locking direction so gear 22 can't rotate, and can not promptly prevent the loosening of turnbuckle towards moving back loose measure to rotation.
Shown in Fig. 3,4, described locking gear 2 is a hoop-tight organization, comprises screw thread compact heap 31 and the screw 32 of hoop outside screw rod 8, links to each other with slide block 4 by straight pin 33; The screw 32 that screws up with a wrench during use, the diameter at bottom of thread of screw thread compact heap clamping screw 8 under application force prevents to become flexible, the advantage of this embodiment is, the area of contact of screw thread compact heap 31 and screw rod 3 is big, and what press is the internal diameter of screw rod, can not damage the screw thread on the screw rod 8 by pressure.
